Airports in Atlantic Canada quickly filled with thousands of bewildered people who had been flying west across the …

Climate scientists have tracked the growing percentage of carbon dioxide (CO2) in the air, and noted a correlation between that rise and global warming. Scientists from Michael Mann to Benjamin Santer have measured the changes in CO2 levels against climate change, with 97 out of 100 climate scientists accepting that human activities and rises in CO2 (and other greenhouse gases such as methane) are affecting our overall climate. Not to start an argument about this matter, this entry looks at a novel method of removing CO2 from the atmosphere and using it to make possible carbon materials that would be used in aerospace and other components. The question of carbon removal usually includes some method of storing it. Futurism.com has …

Dr. Benjamin Santer is a renowned climate scientist, leading the Intergovernmental Panel on Climate Change (IPCC) when it won the Nobel Peace Prize (along with former Vice President Al Gore) “”for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change.” The IPCC clarified the award by explaining, “The prize was awarded to the IPCC as an organization, and not to any individual associated with the IPCC.” Even though he fought through the idea that mankind was adding to the warming trend over the last 100 years*, and risked his career at several points along the way, overall, scientists worldwide have come …
